To all whom it may concern.-

Be it known that I, OTTO KLATTE, a subject of the King of Prussia, German Emperor, residing at Neuwied-on-theRhine, Prussia, Germany, have invented certain new and useful Improvements in 'Rolls for Chain-Rolling Mills, of which the following is a specification.

My invention relates to a rolling mill of the kind described for chain bars in my application for patent filed March 8, 1892, Serial No. 424,127, but "the invention is also applicable to rolling mills for the manufacture of smooth bars or bars with impressions of any kind.

Foreign patents have been granted for this invention as follows: in France, No. 232,132, dated August 11, 1893; in Belgium, No. 106,021, dated August 18, 1893; in Italy, No. LXVIII, 88, dated September 30,1893; in Norway, No. 3,391, dated August 16, 1893; in Luxemburg, No. 1,874, dated August 10, 1893, and in Great Britain, No. 15,403, dated August 12, 1893.

In the application for patent referred to the rolls are shown as consisting of six die disks held together by means of securing disks. Instead of these rolls it is now proposed to use rolls which can be constructed more simply. According to the present invention each roll is constructed by placing a tire like ring, the periphery of which has grooves or cavities to correspond with the chain links to be formed or with any other impressions to be made respectively with the section of the smooth bar to be rolled, on a core disk of the same width, and fastening the two securely together.

A roll constructed in the manner just de-v scribed, in comparison with a roll composed of a single disk or of several disks secured together, has the advantage that the renewal and substitution of worn rolls is considerably cheaper, as the core disk can always be used again. This roll is illustrated in the accompanying drawings, in which a Figure 1 represents a vertical section through the roll. Fig. 2 shows a side View of thecore disk-with the tire disk in position. Fig. 3 is a vertical section on an enlarged scale through four such rolls where they meet together.

t 1 is the ring disk and 2 the core disk on which the roll disk is simply pushed from the.

side. The rotation of the roll disk on the core is prevented by means of two or more keys 3 Fig. 2, which are driven partly in a groove in the roll and partly in a groove in the core. Aclamping or securing disk 4 Fig. 1 is placed on each side of the body so formed and these disks are then firmly connected to the roll disk by bolts 5, which pass through holes in the disks and in the roll disk. The clamping disks and the core each have a central hole.

The shaft 6 Fig. 1 of the roll is passed through these holes until one of the clamping disks, in Fig. 1 the left, comes in contact with a disk 7 forming with the shaft one piece or fixed to the same so as to form a flange thereon. Another flange disk 8, similar to the disk 7, is then pushed on the shaft from the opposite end and fixed to the shaft by a Wedge or other means for preventing its turning and the parts 2, 4, 7 and 8 are then finally connected by bolts 9, which pass through holes in the said parts. The holes in the core disk 2 and the clamping disks 4 for the bolts 9 are made oval Fig. 2, so thaton loosening the bolts 9 the parts 1, 2, 4, 5-can be revolved to a certain extent on the shaft and in this manner the grooves or cavities 10 Fig. 3 can be brought into the correct position relatively to those of the other three rolls. This having been done, by tightening the nuts of the bolts 9 a frictional resistance will be produced between the disks 7 and '8 on the one hand and the parts 1, 2, 3, 4, 5 forming a hole on the other hand, which resistance serves the purpose to maintain the parts 1, 2, 3, 4, 5 in the position given to it with relation to 7 and 8.

The thickness of the roll disk and of the core disk depends on the size of chain to be formed. In order, however, to enable the same rolling mill to be used-for chains of various sizes the total thickness of the roll or core disks and the clamping disks must always remain the same. When therefore, the ring is made thinner the clamping disks must be made thicker and with a thicker roll disk the clamping disks are made correspondingly thinner. In the case of very thick roll disks the clamping disks 4 are done away with and the outer disks 7 and 8 are used as clamping disks.

In this manner the shaft and the outer 1o 1 disks 7 and 8 as Well as the whole rolling mill can be used for chains of various sizes and shapes.

By providing in combination with parts 1, 2 and i the keys 3 and bolts 5, it becomes possible to assemble the operative parts of a roller in their proper relations to each other previous to mounting the same on the roller shaft, thereby saving time when it becomes necessary to change from one pattern or cross'section of the article to be rolled to another; and further, as all these parts are united into one body, the adjustment of the grooves and cavities on the periphery of a roller with reference to those on the other three rollers can be easily accomplished through the instrumentality of bolts 9, 9 as heretofore described.

Having fully described my invention, what I desire to claim and secure by Letters Patcut is 1. In a roll, in combination with its shaft, a central portion carrying the operative roll surface and being movable around its shaft,

a fixed flange and a detachable flange on said shaft and facing opposite sides of said central portion, and bolts passing through said central portion and said flanges, said central portion provided with elongated holes for-receiving said bolts, for the purpose of adjusting the relative position of central portion and flanges with reference to each other and with Feference to the shaft, substantially as set orth.

2. In a roll, in combination with shaft 6 and fixed flange 7, core disk 2, roll disk 1, keys 3, clamping disks 4, 4, bolts 5, 5, detachable flange S and bolts 9, 9, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

OTTO KL ATTE.
